PILE HEAD JOINT STRUCTURE AND PILE HEAD JOINT METHOD
To provide a pile head joint structure and a pile head joint method which can bear a compressive axial force from a foundation part with a connection part while lowering a degree of fixation of a pile head joint part and achieving half-rigid connection.SOLUTION: A pile head joint structure 1 has a pile 2, a foundation part 3 provided above the pile 2, and a connection part 4 that extends in a vertical direction and whose lower side is embedded coaxially with the pile 2 and upper side is embedded in the foundation part 3. The connection part 4 has a steel pipe 41 extending in a vertical direction, an outer diameter of the steel pipe 41 is 1/6 time or more and 1/3 time or less of a pile diameter, the pile 2 has a pile body 27 and a cross section reduction part 26 that is provided coaxially with the pile body 27 and projects above the pile body 27, and the foundation part 3 is connected to the cross section reduction part 26 so as to transmit the axial force and is insulated from an outer peripheral part 25 of the pile body 27 so as to prevent the axial force transmission, and an outer diameter of the cross section reduction part 26 is 0.6 time or more and 0.7 time or less of the pile diameter.SELECTED DRAWING: Figure 1
【課題】杭頭接合部の固定度を低下させ半剛接合としつつ、接続部で基礎部からの圧縮軸力を負担することができる杭頭接合構造および杭頭接合方法を提供する。【解決手段】杭２と、杭２の上方に設けられる基礎部３と、上下方向に延び、下部側が杭２に同軸に埋設され上部側が基礎部３に埋設される接続部４と、を有する杭頭接合構造１において、接続部４は、上下方向に延びる鋼管４１を有し、鋼管４１の外径が杭径の１／６倍以上１／３倍以下であり、杭２は、杭本体２７と、杭本体２７と同軸に設けられ杭本体２７の上方に突出する断面縮小部２６と、を有し、基礎部３は、断面縮小部２６と軸力伝達可能に接続され、杭本体２７の外周部２５と軸力伝達不能に絶縁され、断面縮小部２６の外径は、杭径の０．６倍以上０．７倍以下である。【選択図】図１
